Repit: Adaptive language tutor のアプリ分析 9月8日

When we first started speaking, how many rules of English grammar did we know? Five? Maybe fifty? Of course not a single one — we simply repeated the words and phrases we heard from those around us. So why do we focus so much on grammar when learning a new language? If we were able to start speaking our native language without even knowing what verb tenses were, there must be a way to bypass all the tedious grammar routines when learning new languages. We thought deeply about the mechanics of this process and created a language-learning app without a single grammar rule inside, where the entire learning process is controlled by just one button.
